Abstract (en)
[origin: EP1729404A1] The motor has two rotors (1a, 1b), and circular blocks (4a, 4b, 5a, 5b) including an active material part for rotors spinning through their synchronous deformations. The rotor is made of a material of an alloy constituting aluminum, iron and a material selected from a group consisting of vanadium and silicon, cerium, molybdenum, ytterbium and gadolinium, chromium and titanium and vanadium, where the aluminum constitutes 80 percent weight of the alloy and the iron constitutes 1 to 15 percent weight of the alloy.
